Our Factories

Inside the Prolonged Hair Factories

Every strand we sell begins inside facilities we own and operate exclusively — never outsourced, never shared, never open to another brand. Across our processing operations, a single bundle is tracked from donor intake through our proprietary line to final delivery. We are the only vertically-integrated hair extension brand that controls every facility in its chain, and this is where that promise is kept.

Our facilities operate on the Provenance-7 protocol — seven documented checkpoints between donor intake and final bundle, including our signature low-temperature "cold-seal cuticle lock" stage, applied identically across every site we run.
